FILLER.

SPECIFICATION forming part of Letters Patent No. 388,249, dated August21, 1888.

Application filed October 26, 1887. Serial No. 253,481.

To all whom it may concern:

Be it known that I, GEORGE BLUM, a citizen of the United States,residing at Newark, in the county of Essex and State ofNew Jersey, haveinvented certain new and useful Improvements in Powder-Fillers; and I dohereby declare the following to be a full, clear, and exact descriptionof the invention, such as will enable others skilled in the art to whichit appertains to make and use the same, reference being had to theaccompanying drawings, and

to letters of reference marked thereon, which form a part of thisspecification.

The purpose of this invention is to provide [5 a device for fillingsuitably-prepared receptacles with sedlitz or other powders, which iscompact in construction and of small size, so

that it may be easily operated by one hand,

and which may be made at very little expense.

Heretofore in preparing sedlitz powders for sale the powder is firstmeasured in cups of the required capacity and the powder deposited inunfolded papers of the required size which are afterward folded by hand.This evidently requires a great deal of handling, and hence occupiesmuch time in preparing the powders for sale, and, moreover, owing to thethickness of the folded paper, a box of considerable size is necessaryto hold the required number of powders.

My invention is designed to obviate the extra handling of the powder andthe paper, to enable a greater number of powders to be prepared in agiven time,and to reduce the size of the package containing the powder,and hence permit the use of a much smaller box for the same number ofpackages.

In the sheet of drawings herewith accompanying, in which similar lettersof reference in- 4: dicate corresponding partsin each ofthe views,Figure l is a side elevation of my improved filler inserted in a powderpaper or envelope, showing the position of the parts just before thepowder is expelled from the powder-chamber into the envelope. Fig. 2 isa view of an envelope which is used to receive the powder. Fig. 3 is asection taken through m, Fig. 5; and Fig. 4 is a front elevation of myimproved filling device. Fig. 6 is a section taken 50 through g on Fig.5, illustrating the position of the parts when arranged to receive the(No model.)

smaller quantity of powder or tartaric acid designed for the whitepaper.

In the above views, (L indicates the receptacle havinga powder-chamber,a,within, which 5 receives the powder, said receptacle being preferablysharpened or tapering at the end which is inserted into the powder andalso into the powder-envelope to more readily permit the insertionthereof. Extending through the bottom of the receptacle a, and openinginto the chamber a, is a perforation through which works a plunger, I),having on the end within the powder-receptacle a head, I), which is ofsufficient size to fill said powder-chamber and still permit the same tomove reciprocally within the same.

Encircling the receptacle a is a plate, 0, which acts as a guard toprevent the powder into which the receptacle is inserted from adheringto the fingers of the hand which holds the filling device, hooks orfinger-pieces (I being formed on or secured to the end of the receptacleback of the guard c, by which the filler is held in the hand. Said hooksmay be riveted orotherwise secured to the receptacle, or may be formedor cast integrally therewith, as may be desired; also, the guard may beriveted or otherwise secured around the receptacle. WVhile the use ofthe said guard is considered advantageous, still the filling device maybe conveniently used without said guard, particularly when thereceptacle is made of considerable length, or when the fingerpieces orhooks are made to extend back- 8 ward away from the bottom of thereceptacle.

As indicated more particularly in Figs. 3 and 6, the plunger 1) istubular, and is provided with a slot, If, on one side thereof extendingfrom the stop 1) down to or nearly to the head, 0 and within saidtubular spindle is arranged a spiral spring, bflone end of which abutsagainst the finger-piece I) and the "other end projects through the slotb and is preferably wrapped around the outside of the spindle, thusacting 5 to hold the lower end of the spring stationary, so that it willbe compressed when the plunger is moved into the powder-chamber, andthereby store up sufficient force to withdraw by its expansion theplunger from the open end of the powder-chamber and restore it to itsnormal unoperated position, as indicated in Figs. 1 and 3, at the bottomof said powder-chamber.

While I have illustrated and described this peculiar arrangement of thespring within the plunger, I do not wish to be understood as limitingmyself to this particular arrangement and construction, as said springmay be otherwise arranged to produce the desired movement of the plungerwithin the chamber in the receptacle; in fact, I may dispense with thespring altogether and move the plunger in the chamber by hand. As thusconstructed, the spring acts to throw the head down into and against thebottom of the powder'chamber, leaving a large space between the saidhead and the mouth of the chamber, which, when used in preparing sedlitzpowders, is of sufficient capacity to hold the quantity of powderdesigned to fill the blue paper.

In order that the same device may be used to measure the desiredquantity of powder to fill the white paper, or that containing thetartaric acid, I have provided a slot, 22, extending from the stop I)along the tube a sufficient distance, which is determined by the lengthof the space between the head and the end of the powder-chamber. Intosaid slot b a set-screw, or, projects and limits the movement of theplunger according to the length of the said slot 1). While I havespecifically described and illustrated this form and construction ofdetaining device, I do not wish to limit the scope of the inventionthereto.

The operation of the device is as follows: Two of the fingers areinserted through the hooks d and the thumb placed upon the end of theplunger, and the mouth of the filler is inserted and pressed down intothe powder and is then lifted therefrom, carrying the contents of thepowder-chamber with it. The tapered end of the filler is then insertedinto the envelope, and then by the pressure of the thumb upon theplunger the downward movement of the head forces the powder from thechamber into the envelope,which is then sealed up and is finished readyfor packing. After a sufficient quantity of the combined soda and salthas been prepared in the blue envelopes the plunger is adjusted to theposition indicated in Fig. 6, and the same operation is repeated withthe tartaric acid,which is placed in the white envelope.

Having thus described my invention, what I claim is 1. A powder-fillingdevice consisting of a powder-receptacle having finger-hooks thereon,anda guard around said receptacle between the hooks and the end of saidreceptacle which is inserted into the powder, and a plunger workingwithin said powder-chamber,whereby the powder is expelled from saidpowder-ch amber, substantially as specified.

7. A powder-filling device consisting of a powder-receptacle providedwith a powder chamber therein and finger-hooks thereon, aspring-actuated plunger moving within said powder-chamber and providedwith a slot, b therein, and a set'screw arranged in saidpowder-receptacle and adapted to engage with said slot 1) in theplunger, substantially as and for the purposes set forth.
